I just spent almost a day trying to solve this issue. Following this thread, I started by changing the blit type to never/always/auto without any success.

My project is using unity 2018.2.5f1 + Lightweight renderer. Everything was looking fine until I added a hud camera with the clear flag to Depth only.

Then, I installed and tried all the variants on 2018.2.12f1 and 2018.3.0b5. Same blackscreen.

I started to mess around with every properties that seemed related. I've found that LightweightPipeline -> Render Scale is equal to 1 *AND* that LightweightPipeline -> Depth Texture is DISABLED, it fixes the black screen issue.

I don't totally understand the internal issue here but it's a shame that the Render Scale property isn't working :( I was hoping to tweak this value a lot since our vuforia game is draining to much cpu and power.

The issue is still reproducible. Used Unity 2018.2.1f.
Is't really fixed? Could you please provide the "future version" where it is fixed?

Leaving a comment incase anyone else encounters the form of this issue where the game is transparent rather than black as what happened in my case.

It caused the app to just not render rather than render black making the last frame of whatever was on the screen as you launched or switched to the app just appear frozen on the screen. (However the app can still be used as normal, it's just that you can't see anything)
